CARBURETER.

To (all, '071.01711 it muy concern:

Be it known that I, AUGUSTE Goss, civil engineer', a citizen of France, residing at Petit-Bourg, Seine and Oise, in the Republic of France, have invented new and useful Improvements in Carbureters, of which the following is a specilication.

This invention relates to an improved construction of carburetcr for internal-combus tion motors which insures by very simple means a regular action of the apparatus and constant composition of the mixture at diti'erv ent speeds of the motor, the said carburetcr being at the same time of great strength and occupying a very small space.

The apparatus principally comprises, in addition to the usual constant-level feed, a vertical chamber having a conical interior wall widening toward its upper end and adapted to receive the air at one end and a movable conical member also vertically disposed and displaceable in the aforesaid chamber in an axial direction for the purpose of regulating the annulal` section of the air-inlet passage. The said movable member is adapted to move freely and may be simply under the action of a spring, so that the variations of speed of the motor create varying degrees of depression in the carburetcr, which cause the displacement of said mov able member, thus producing variations in the annular section of the air-inlet passage proportionally to the speed of the motor and insuring a constant carburization. The said movable member can also be operated mechanically by a movable part of the motor, according to the speed ot' the latter.

The invention also relates to the novel arrangement and combination of the component parts of the carburetcr, or' which the following description will explain the action.

In the annexed drawings, Figure 1 is a vertical section o'f the complete carbureter, showing a construction in which the movable member is automatically regulated by the suction of the motor. Fig. 2 is a horizontal section on the line A A of Fig. l. Fig. 3 is a section on the line B B of Fig. l, showing the fuel-supply cock. Fig. 4 is a vertical section, partly in elevation, of a carbnreter with mechanically-operated movable member.

Fig.

5 is a partially horizontal section on the line C C of Fig. 4, showing the means for mechan* ically operating said movable member.

Referring to Figs. 1 to 3, it will be seen that the carburetcr comprises an ordinary constant-level feed f1 andthe body of the car bureter proper. The latter comprises a vcrtical conical chamber I), having its wider end at the top, this chamber communicating at its lower endwth at is to say, its smaller endwith the air and fuel supply and at its upper end with the suction-space of the motor. Axially within the chamber l) is located the movable member or light hollow cone c, with its wider diameter above' and guided at both ends by rods (Z and e, one of which, d, is Iixed to a spiderfand passes easily through the upper end of said cone c. The other rod c is iixed to the lower end of the cone c and slides in a casteil-on bracket g, connected to the walls o'l the chamber l). The cone c regulates the annular section of the air-inlet produced between itself and the walls of the chamber l), so that by displacing the cone longitudinally this section can be varied. A spring 7a, the tension of which is adjusted For each motor, tends to press the cone c downward. According as the degree oi' depression inthe chamber l), produced b y the suction of the motor, increases with the speed of the motor the cone cis more or less raised, thus increasing the annular section et' the air-passage and automatically maintaining constant composition ol" the mixture. The air passes into the carburetcr through the radial apertures fi, arranged around the bracket g, the latter being in the form of a spider with hollow wings or arms 7c and its lower part being hollow for reception of the circulation-water from the motor, water at the same time also passing into the arms r, and thus partly heating the air on its way to the mixing-chamber. A similar circulation takes place in the acket surrounding the chamber l) of the carburetcr. The inlet of liquid fuel to the carburetcr preferably takes place through the small channels Z, arranged between two conical surfaces around the air space or inlet. Between the constant-level feed and the body of the carburetcr a regulating-cock having a pin-valve or the like m will usually be arranged for con- IOO llO

trolling the passage of the liquid, and in the upper part of the mixing-chamber is arranged a damper 72, controlled by the governor.

Referring to Figs. 4 and 5, it willbe seen that the component parts of the carbureter remain the same as in tne construction dcscribed, with the exception that the movable member or cone c instead of being displaced automatically by the suction of the motor is operated mechanically by a lever p, connected by means of a spindle q, fixed to said lever, and an exterior arm r to a part of the motor, the position of which varies according to the speed-for instance, the device for controlling the ignition. The spring h is then dispensed with, Constant carburization is by this means also completely assured, since the movable member c is raised or lowered mechanically by degrees as the speed of the motor increases or decreases, thus proportionally augmenting or diminishing the section of air-passage to the carbureter.

Having now described my invention, what I claim as new, anddesire to secure by Letters Patent, isM

1. A carbureter comprising in combina'- tion a vertical conical chamber b having its larger end uppermost, a water-jacket a; sur rounding said chamber, inclined channels Z for the inlet of liquid fuel arranged around said chamber at its lower part, a liquid-fuel receptacle with constant-level feed a in communication with said channels, a cast-metal bracket g attached to the lower part of said conical chamber below the inlet-channels, radial apertures i in said bracket for the entrance of air to the chamber b, hollow wings 7c between said apertures communicating with the hollow bottom of the bracket for the circulation of heated water, a movable vertical hollow cone c having its larger end uppermost and located in the axis of the aforesaid chamber, and means for guiding said cone in its longitudinal movements substantially as described and for the purpose set forth.

2. A carbureter comprising in combination a vertical conical chamber b having its larger end uppermost, a water-jacket :c surrounding said chamber, inclined channels Z for the inlet of liquid fuel, arranged round said chamber at its lower part, a li uid-fuel receptacle with constant-level fee a in communication with said channels, a cast-metal bracket g attached to the lower part of said conical chamber below the inlet-channels, radial apertures i in said bracket for the entrance of air to the chamber b, hollow wings lc between said apertures communicating with the hollow bottom of the bracket for the circulation of heated water, a movable vertical hollow cone c having its larger end uppermost and located in the axis of the aforesaid chamber, means for guiding said cone in its longitudinal movements, a lever p in engagement with said cone c, a spindle g fixed to said lever, and an operating-arm r keyed to the spindle outside the apparatus, substantially as described and for the purpose set forth.

In testimony whereof l have signed my nameto .this specification in the presence of two subscribing witnesses.
